<P>PROBLEM TO BE SOLVED: To provide an apparatus for optimally estimating transducer parameters that determine linear parameter and non-linear parameter without system errors, even if a model for linear characteristics of the transducer is not perfect. <P>SOLUTION: The apparatus and method for optimally estimating transducer parameters are provided with a transducing system 55, having a first transducing input terminal 61, connected to a transducer input terminal 7 for receiving an input signal x(t) to the transducer 1; a second transducing input terminal 57 connected to a transducer output terminal 9 for receiving an output signal y(t) of the transducer 1; first transducing output terminals 67 and 69, generating time signals in which information of linear signal component y<SB>lin</SB>(t) contained in the output signal y(t) is suppressed, and the information of the non-linear signal component y<SB>nlin</SB>(t) contained in the output signal y(t) is retained and second transducing output terminals 63 an 65 for retaining the information of the linear signal component y<SB>lin</SB>(t). <P>COPYRIGHT: (C)2008,JPO&INPIT |
